To all whom 'it may concem:

WELCI-I,'fl citizen'of the United States, re-

siding at Aurora, in the county of Kane and State of I inois, haveinvented certain new and usefuqlmpi-ovements in Folding Elesv aspecificavators, of which the'following'i tion, reference being ingdrawings, v

Mv'invention relates to machines for han- "plicable to .other uses, buthas particularly .to do withmechanism forelevating or con- "veyingmaterials,

such as. crushed. stone, etc in connect on with road-making, gradmg .andother analogous work.

v I 'The object of my invention is to provide 1' a new and improvedconstruction by which the elevator may readily be folded for transportation purposes or extended for use. I accomplish thisobjct asillustrated in the drawings and as hereinafter described.

v What I regard as new is set forth in the claims.

stone-crusher which may be 'andl 3, which are rigidly secured thereto,Be it known that I, SAMUEL FRANK'Z preferably by bolts 17, as shown inFig. 4, from which it will be seen that said arms project ashortdistance to the left of the uprights and a greater distance to the right16 carry pulleys or sheaves l8, and at their longer ends they areprovided with pulleys as best shown in Fig. .4. The several pulwill behereinafter described.

' 21 indicates braces by which the longer ends of the horizontal arms15-16 are braced from the uprights '13-l4, as best 22 indicates anendless conveyer, preferably of the bucket type, which is mounted upon ahinged frame, the construction of which is best shown in Figs. 1, 2 and3. Said frame is composed of two. parallel members, preferably tubes,each composed of a lower member 23 and an upper member 24 whicharehinged together, as shown at .25 in Fig. 3., The hinge of said membersis also shown in Figs. 6 and 7. As therein shown, a single pivot 26serves as the hinge for both side members of the elevator frame.

27 indicates an intermediate brace for the upper members 24, and 28 asimilar brace thereof. At their shorter ends the arms leys form fulcrafor the hoisting ropes as' for the lower members. 23 of the elevatorframe.

29 indicates a shaft which connects the lower ends of the members 23,and also carries sprocket-wheels 30 or a pulley around which theendless conveyer 22 passes. In-

.the shaft 31 and driven by a chain 38 from 1 which is mounted on a asprocket-wheel 39 shaft 4Q journaled in suitable-bearings carried by thelower members 23 of the ele-' vator frame, as shown in Fig. 3. Saidshaft is provided with a pulley 41 which is driven 55 anatieallyraisedclear" 075 bv a belt 42 froma pulley 43 carried by the main shaft 44 ofthe stonecrusher as shown in Fig. 1. Thus the endless conveyer 22 isdriven from the n'iechanism which operates the stone-crusher.

hi l6 indicate cables, the upper ends oi which are connected to theouter end. portions of the side members of the elevator frame. as shownin Figs. 1 and 2, and. pass between. the pulleys ill--20 and down todrums 4 -'l8 mounted on a shaft 49 which is suitably supported by theuprights 13-l'i, as shown in Fig. 3. Said shaft is provided with a gear50 which meshes with a pinion 51 mounted on a stud said gear being prvided with a hand-Wl'ieel 53 by which it may"be rotated. ".hus aWindlass is pro video. for drawing in or paying out the cables .257% andthereby raising or lowering the outer end portion of the elevator.

"""he elevator is pivotally connected with the uprights by means ofstraps 5%, one at each side, which .ut one end are connected with theside members of the elevator frame in line with the pivot 26 and attheir other ends are connected with the uprights l3ll by pivots as shownin Figs. 1 and 2. straps, therefore, act links which afford a swingingor traveling connection between the elevator frame and the uprights13-ll, causing the pivot 26 to swing in the arc of a circle about thepivots 55 a center. 56 indicates another pair of straps or links Whichare pivoted at their upper ends to theuprights 13-4 1 by pivots 57,which; are placed lower than the pivots 55, as; shown in Figs. 1. and 2,

and at their lower ends the links are connected with the lower membersof the elevator frame byl When the elevator frame is in its extended oroppivots 58 as shown in said figures.

erative position, the lower linlrs 56 are almost vertzcah-as shovn inFig. i, butwhen the ele 'ator frame is folded Said links ex;

tend almost horizontally. as shown in Fig. 2,

carrying the lower portion of the elevator frame up bodily and moving itout into a substantially vertical position, as illustrated.

fill-60 indicate supports, preferably ers, which are carried by theuprights MB-i i preferably on brackets 61. in such position that theyunderlie the upper members of the elevator frame when folded, as sh wnin Figs. 2 and 3, thus supporting said irame when folded. Said rollersalso serve to lolcrum the upper members of the-elevator frame when theelevator is being folded or swung back into inoperative position. Forexample, as the elevator is folded back at the hinged point. the membersof the upper section strike and rest upon said rollers fill--00 whichact as rolling fulcra for said members, and as the movement continuesthe lower section of the elevator frame autoshe ground; the

1 V l I l elevator as a. Whole being held and guided to proper positionby means of the links 55 7-56. When the elevator is again raised tooperative position, this movement is re -versed and the partsautomaticallybrought to and securely held in proper position.

62 indicates a bail secured to the side mem bers of the elevator frameand extending at right angles thereto, as shown in Figs. 1

and 2, so that when said elevator frame is folded, as shown in Fig. 9.,it will rest upon a portion of the stone-crusher 9 and assist insupporting the elevator frame. 63inchcates braces for said. baih Fromthev foregoing description it will be seen that when the elevator frameis in its operative position. the upper and lowermembers thereof are inline, the elevator frame being then supported by the cables 45-46 whichbear upon the pulleys 20. The lower end of the elevator frame is hold inposui'onby the links M and the ends of the pivot 58 also engaging theuprights ill-1 as shown in 3. and sewing to prevent the lower end ol'the elevator frame from swinging in too far. In this position the lowerportion of the elevator receives the discharge from the stone-crusherand ele' rates it for delivery. W hen the apparatus to be transported,by operating the WlI1Cllass the upper end of the elevator 18 pulled overtoward the uprights and then swung ver, the cables running on thepulleys 19 until the parts finally assume the position.

shown in Fig. 2, the ca les. then running also on the pulleys 18. At thesame timeithe lower members of the elevator frainez are automaticallyraised by the swinging. of'the upper member of the elevatorframe uponthe rollers or supports lf 9-6ll as -ifulcra.in

themenner already described and are can ricd outward and upward by thelinks o l-56, as shown in Fig. 2, so that they assume a verticalposition. When thopar s are fully folded, the upper members of theelevator frame arein a horizontal position resting on the bail (32-which engages a portionot' the stone-crusher. li/Wlll be apparient thatafter the elevator frame swings past the center in folding it isnecessary (to 15 pay out on the cables in order toallow the uppermembers of the elevator frame to swing downward to their horizontalposition, and that they'may be restored 'to their operative position bydrawing in the cables until the upper portion of the elevator frameassumes a vertical position and swinging it past the center, when itwill. again assume the position shown in Fig. 1'.

Instead of using the ha-nd'wheel' and spurgear shown in the draWings-any other suitable construction s nay be employed for actuating thehoisting devices, as, for instance, a worm and crank shown in Fig. l inwhich 641: indicates a cranlr operating; the-Won 1 65 nsea sary wherethe spur gear is used and making it impossible for a careless operatorto drop the elevator to the injury of the elevator or of himself orothers. In other respects also my invention is not restricted to thespecific details shown and described, except in so far as they areparticularly claimed, but in-v cludes generically the sub ect-niatterofthe broader claims.
